I have had this happen too many times to count. Presumably, husband and wife. One is a twig..... one 5X a twig. Twig takes the aisle or window and leaves the COS in the middle seat spilling over massively. Come on people.

I'm sitting on a 6 hour flight in the back of coach due to 5X twig pax hanging over 1/4 of my PC seat so I asked to be moved. I was on an upgrade and it's not even so much a monetary thing. More a human decency and kindness thing.
